دانلود کتاب Elementary Differential Equations and Boundary Value Problems , 8th Edition, with ODE Architect CD

First a little bit of annoyance, actual review below-
the kindle version is $95! It should be below $44 before it is worth buying at all. If I buy the real textbook for $144 on here, I can sell it for about $100 after I'm done with it, so it costs me $44 for the semester. If I buy the kindle version I am paying twice as much to look at the book on a tiny ereader.

Contrary to what many others have said, I found this book pretty decent. I think much of how you will value this book has to do with the teacher of your class and what type of class it is. I actually barely used it because my teacher was so good, so maybe I just didn't get the full experience. This definitely doesn't compare to Friedberg et al's insane book on Linear Algebra, but it is ok. Used for an upper division ODE class with all math majors, I thought it hit the spot. Not the kind of textbook you read anyway, it is an applied math textbook. That being said, there was no reason that it needed to be so big, heavy, and expensive.
